At the 2024 Watches and Wonders fair, storied German watchmaker A. Lange & Söhne unveiled its latest masterpiece: the DATOGRAPH PERPETUAL TOURBILLON HONEYGOLD “Lumen.” This new interpretation of Lange’s iconic DATOGRAPH line showcases the brand’s expertise in high complications and innovative materials.

The DATOGRAPH PERPETUAL TOURBILLON HONEYGOLD “Lumen” combines a flyback chronograph, perpetual calendar, and one-minute tourbillon with stop-seconds mechanism, all powered by the new manufacture calibre L952.4. The 684-part movement assembles each component with meticulous care twice over to ensure perfection. Visible through a sapphire caseback, the movement features Lange’s signature finishing like German silver bridges, polished chatons, blued screws and a freely oscillating balance spring with poising weights.

Beyond mechanical mastery, the watch’s harmony of form and function shines. The chronograph, calendar displays and time indications radiate in balanced elegance on the dial. At night, the “Lumen” version glows, with luminous hands, dials and even the outsize date. This limited edition of 50 pieces marks only the second Lange watch to use the brand’s proprietary 18k honey gold alloy, which offers hardness and remarkable radiance.

“In 2016 our engineers created one of our most sophisticated watches in the DATOGRAPH PERPETUAL TOURBILLON,” said Anthony de Haas, Director of Product Development. “With the new ‘Lumen’ edition in honey gold, we spotlight its technical and aesthetic highlights while introducing the ability to experience them in the dark.”

Once again, A. Lange & Söhne pushes boundaries in mechanical watchmaking. The new DATOGRAPH PERPETUAL TOURBILLON HONEYGOLD “Lumen” combines complex innovations and exquisite design to create another future classic for the brand. Its harmonious precision, glowing allure and limited availability certify the watch as a new pinnacle of haute horlogerie.
